Update organisms warning text

[frano-m]

Update the warning text; the text no longer matches the UI experience.

If you do not see your organism in this list: it will be there! We are in the process of ingesting sequences and annotations for all 785 taxa from VEuPathDb. The table below is generated by comparing the list maintained by VEuPathDB against official NCBI genome builds. The three buttons adjacent to each taxon direct you to a page listing available analytical workflows as well as direct links to genomic data (NCBI Datasets) and a genome browser (UCSC). A comprehensive search functionality will be developed to allow complex queries.
